It then grew to nearly 5,000 restaurants; by 2013, Quiznos was the second-largest submarine sandwich shop chain in North America, behind Subway. It filed for bankruptcy in 2014; by 2016, it had dropped to ninth place, and the number of Quiznos locations in the United States fell from a 2007 high of 4,700 to just 400 a decade later.
